Specification of Letters Patent.

Application filed February 10, 1910. Serial No. 543,069.

To all whom "it may concern.

Be it known that I, RUDOLPH G. WINTER, of Milwaukee, Wisconsin, have invented a Shutter-Bower, of which the following is a specification.

This invention has for its object to provide a lock for suspension-sashes, and may be considered as an improved form of the device described and claimed by me in my United States Letters Patent No. 641,745, issued January 23, 1900.

The present improved form of fastener is adapted either for attachment to the center of the sill and lower sash-rail or to the side of the window-frame, as for instance on the blind-stop, where it is out of the way. Besides the novel principle of design necessitated by such adaptation I further aim to form the principle of action of the lock whereby in the locked or closed position of the sash any force acting upon the sash tending to open it will act to hold the lockrod more firmly in locked position so that it cannot possibly become dismounted by any force exerted upon the sash.

One of the principal novel features of my present form of shutter-bower consists in making the lock-rod of a flattened strip instead of a round wire as heretofore; this gives it a much greater resiliency when bent into the novel form now first disclosed.

Another feature of the invention consists in the peculiar s-hook formed on the sashend of the rod which has the double function of engaging a fixed lug in the closed position of the sash and of providing resiliency in the open position.

Other features of my invention will appear from the accompanying detailed description and are particularly specified in my claims.

In the accompanying drawings I have shown two forms of my improved shutterbower, the first adapted for use upon the side of the sash and the second in the center thereof.

In these drawings, Figure 1 is a side elevation of the first form in position, with parts of the sash and window-frame shown in fragmentary crosssection; the parts being shown in open position; Fig.2 is a similar view with the parts in closed position; Fig. 3 is a plan view of the same with the parts in open position; Fig. 4: is a projection on an oblique plane of the fixed element; Figs. 5 and 6 are respectively a side view and a transverse section on the plane 6 of the same; Figs. 7 and 8 are respectively a plan view and a side view of the pivot member of the device; Fig. 9 is a side view on an enlarged scale of the sash-end of the lock-rod; Figs. 10 and 11 are respectively a plan and a front view in closed position of the second form of my shutter-bower, including parts of the window-sash and sill; Figs. 12 and 13 are similar views and Fig. 14 is a side view of the same parts shown in open position; Fig. 15 is a perspective view, Fig. 16 is a plan view, and Fig. 17 is a side view, of the fixed member of the device; and Figs. 18 and 19 are respectively a plan and front view of the pivot-member of the same.

In these drawings every reference letter and numeral refers always to the same part.

Describing first the sidefastener as shown on Sheet 1 of the drawings, I have shown only the left-hand fastener but it will be understood that in general one will be placed on each side of the sash, these being. symmetrical with each other, or as it is known in the trade, right and left pairs. I have so devised my fastener, however, that each of the three elements which composeit can be used either as a right-hand or a lefthand fastener as desired, which saves unnecessary duplication of patterns and cast-- ings. Said three elements are designated respectively A, B, C; the first being the fixed member, adapted to be attached to the window-frame or jamb, the second the pivot-member, adapted to be attached to the sash, and the third the lockrod, which is pivotally mounted upon said pivot-member B and engages in two pisitions, to-wit, the

open and closed positions of the the fastener, with the fixed element A.

The element A consists of a plate or base adapted to be set vertically on the edge of the jamb D abutting against the sash E when closed, as shown in Figs. 1, 2 and 3, and having therein a pair of deep notches or slots at which are a notable improvement over screw-holes, inasmuch as they not only admit of a wide latitude of adjust ment relatively to the member C, but also enable the member A to be cast without cores. Now to hold the member A firmly wood of the casing, biting holes thereinto and thus forming a rigid engagement with the windowwasing, preventing such sidewise shifting. On the base rise the lockinglugs a? which are in the form of two posts joined for strengt-hs sake by a bar a across the ends, thus forming an eye or aperture a in which the lock-rod C works.

The pivot=member B, which is secured to the sash in a position opposite the member A, comprises a sortof bail having a central bar 5 which extends out from the sash and acts as a pivot for the member C; and is provided with screw-lugs b 6 on its ends whereby it is secured to the sash. It will be noted that one of these screw-lugs b is smaller than the other, said screw-lug being made as small as possible in order to fit into one of two recesses a on opposite sides of the center of the outer edge of the baseplate of the member A, and still leave a tongue a of maximum width extending out between these recesses, which I have found to be very desirable in order to give the member A a wide and suflicient lateral hearing upon the window-casing and prevent its being loosened by the sidestrains to which it is subjected. F urthermore the screw-lug b is made to fit neatly in either recess a, so that when the two members are in correct relative position on the sash and frame respectively, they engage each other. By this simple device the carpenter is aided in putting up the fastener, as the two pieces can be put together at once in the correct position, rendering any subsequent adjustment or fitting unnecessary. v

Returning to the member B, it may be said that the screw-lug 6 in contradistinction to 6 is madeof sufiicient size to give the latter all necessary bearing upon the sashstile.

The lock-rod C comprises a metal hand, one end of which is bent into a double or S-shaped hook c, a (see Fig. 9), and the other end has a single hook c the end of which is prolonged to form a tongue 0*. The end-loopo of the double hook forms an eye which turns upon the bar I) of the member B, and the inside hook or loop 0 is adapted to engage with the lower lug a in the closed position of the sash, as shown in Fig. 2. It will be observed that in this position the lock-rod C depends vertically in a position *hook c, 0 open.

parallel with the sash, the lower end of said rod resting against the sash, and the tension upon the hook c, 0 thereof exerted by any force tending to open the sash is such as to tend to turn the lock-rod farther in a counter-clockwise direction and make the lock tighter, because in this position the middle bar 0 of the S-shaped hook assumes an oblique position, in which a strain tending to open the sash would make this bar a more nearly horizontal and thus spring the As previously observed, in my improved form the lock-rod C is made of a flattened strip of metal, said strip being given a longitudinal twist of 90 I degrees at a point 0 as close as possible to the bight of the hook c and a second twist c at a point sufliciently distant from the other end to impart the requisite amount of resiliency to the lock-rod to hold the hook c (which is at right-angles to the axis of the rod) firmly in engagement with the post (5* until manually raised therefrom. This is an important feature of my improved shutter-bower, the action of which is dependent on the cooperation of the hooked end 0, 0 with the face of the sash. As will be seen from Fig. 1, the hook c is so bent as to press upon the face of the sash before the lock-rod has been raised sufiiciently to pass through the aperture a, so that the resiliency of the rod springing from the hook c as a base is depended on to cause the hook c to snap over the post a when the sash is opened. To give the rod sufiicient resiliency, it is desirable to have the twist c as close as possible to the bight of the hook c as aforesaid and furthermore such twist is so made as to produce on the inner side of the hook a slight convexity c which cooperates with the face of the post a in such a manner as to further assist in holding the lockrod closed.

In the second form of my invention, Sheet 2 the letter F represents the window-sill and the letter G the lower sash-rail of the window, and the three parts or elements constituting the fastener are designated A, B, C, corresponding in form and function to the parts A, B and C respectively. The fixed member A hasa pair of posts a a, the former of which is engaged by the S- shaped hook of the lock-rod in closed position (see Fig. 10) while the post a has a shoulder (L13 which acts as a support for the lock-rod in the open position (see Fig. 14). In this case the lock-rod C has but one 90- degree twist c, the hook c lying in a vertical plane so as to engage the shoulder a. When the fastener is closed the hook C assumes a horizontal position parallel to the sash-rail as shown. hen the sash is open, the lock-rod C will be tilted with the sash so that the free end thereof would normally lie below the shoulder a on which it runs,

since the pivot consists of the broad flat hook c engaging the middle bar of the pivotmember B, which prevents the lock-rod from having any movement in the vertical plane relative to the latter. Hence, as the sash opens, the lock-rod C is resiliently tilted and pressed against the shoulder a until the hood 0 registers therewith and thereupon snaps thereinto. Thus a springforce is provided in addition to gravity for holding the lock-rod in engagement with the fixed member A in opened position. I may also provide the fixed member A with a projecting edge a and shoulder a destined to engage and cooperate with a corresponding edge Z) and shoulder 22 on the member B so as to assist in mounting the two parts in correct relative position, in the same manner as hereinabove described in connection with the first form of fastener.

While I have hereinabove shown the most improved form of my invention, I wish it understood that not all of the features are essential thereto or necessarily made in the exact form shown, but various changes and modifications in the constructions as herein shown may be made without departing from the spirit of my invention, and I wish it understood therefore that the latter is not otherwise limited than by the proper scope of my claims. It will also be understood that while I have described the invention as applied to a shutter-bower, it could equally be applied to any hinged sash, the parts having the same relative positions with respect to the hinges.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
